OFA ELBOW GRADES

Elbow dysplasia has multiple inherited etiologies which may occur
singularly or in combination. These etiologies include fragmented
medial coronoid (FCP) of the ulna, osteochondritis of the medial
humeral condyle and ununited anconeal process (UAP). The
most sensitive view used to diagnose secondary degenerative
changes in the elbow joint is an extreme flexed medio-lateral
view of the elbow (Figure 1) which is required by the OFA and
recommended by the International Elbow Working Group. The
veterinary radiologists are most interested in the appearance of
the anconeal process of the ulna.

When there is instability of the elbow joint due to elbow
dysplasia, one of the most sensitive radiographic findings is new
bone proliferation (osteophytes) on the anconeal process of the
ulna (Figure 2) associated with secondary developmental
degenerative joint disease.

Bone proliferation can be very subtle to visualize in some dogs
and may require the use of a special light source (hot light)
rather than a traditional view box to diagnose it. Other arthritic
findings such as sclerosis in the area of the trochlear notch of
the ulna and bone spurs at joint edges are also reported. If
fragmentation of the medial coronoid only involves the cartilage,
it may not be seen radiographically but occasionally if the bone is
also fragmented, it can be visualized as a separate calcific opacity
superimposed over the radius (Figures 3 and 4).

For elbow evaluations, there are no grades for a radiographically normal elbow. The only grades involved are for abnormal
elbows with radiographic changes associated with secondary degenerative joint disease. Like the hip certification, the OFA will
not certify a normal elbow until the dog is 2 years of age. The OFA also accepts preliminary elbow radiographs. To date, there
are no long term studies for preliminary elbow examinations like there are for hips, however, preliminary screening for elbows
along with hips can also provide valuable information to the breeder.

Grade I Elbow Dysplasia
Minimal bone change along anconeal process of ulna (less than 3mm).

Grade II Elbow Dysplasia
Additional bone proliferation along anconeal process (3-5 mm) and subchondral bone changes (trochlear notch sclerosis).

Grade III Elbow Dysplasia
Well developed degenerative joint disease with bone proliferation along anconeal process being greater than than 5 mm.
